Admittedly this is a bit tenuous.

What I'm trying to do is write a kernel driver which uses the usb serial
drivers, and not write a poor man's version of usb serial in the IR driver.

Admittedly I don't think it will be much code, so maybe it won't be so
ugly. It's just the code duplication I was trying to avoid.

So, I'll go ahead and as you suggest.

Thank you for your time and thoughts on this.
